⚙️ Key Features

• Genuine Volvo Penta IPS2-C driveline flange
• Applies from serial number 3950003263
• Precision-machined coupling, pilot and retaining surfaces
• Maintains driveline concentricity and torque transfer
• Uses the specified snap ring, casing and flange screws
• Do not interchange across the serial break without confirming the complete drive arrangement

🔌 Function

Connects the IPS transmission output to the adjoining driveline component and transfers propulsion torque while maintaining accurate alignment.

⚠️ Common Signs of Failure

• Fretting, corrosion or movement at the mating face
• Damaged pilot or retaining-ring groove
• Elongated bolt holes
• Abnormal vibration or coupling noise
• Measured runout outside specification
• Incorrect earlier flange installed across the serial break

🛠️ Service Notes

• Clean the taper, key and keyway dry before assembly and check them for burrs, wear and hammer marks; the flange must pull up on the taper, not on the key
• Check the flange face for scoring, corrosion and runout, and the coupling bolt holes for elongation — a distorted flange shows up as vibration under way
• Where a shaft seal runs on the flange, check that running surface is smooth and unworn, because a scored surface will destroy a new seal
• Fit a new locking nut, tab washer or split pin as originally used, and tighten to the figure given in the workshop manual for your installation
• Check shaft alignment and face contact across the coupling after fitting, and re-check the fasteners after the first period of running
